Fusion startups have a solid row from the weeds. Their missions? To create a new type of power plant that produces more energy than taking it – something that no one has done with fusion energy before. This means to prove their technology tasks, it can be shown it can be scale and investors meant it can be done all profitablely. It’s already a tall order. But there is another big challenge that gets very little attention: where to find fuel.
Most fusion startups will say that they will produce their own fuel, thank you very much. And technically, they’re okay. But that answer is glass on top of a key topic: to create tritium – one of the main components of the fusion – they first need a specific isotope of lithium, it is very low supply today.
This thought was spread on Charlie Jerot while working on fusion startup focus energy a few years ago.
“I realize that no one is working on this supply chain staff. Fusion companies have a whole bunch of agencies. There is no company that is about to make fuel for these companies,” he told TechCrunch.
So Jerot and his focused energy fellow Jacob Peterson decided to start their own journey Hexium Fusion is keeping an eye on the future fuel problem solving.
The steel -managed hexium appeared on Tuesday with the $ 1 million seed fund, the company exclusively informed TechCrunch. Mac Venture Capital and Refactor Humba Ventures, Julian Capital, Overture VC and R 7 have led this round with 7 partners.
The main technology of hexium uses decades old methods that use laser to separate lithium isotopes. Atomic vapor laser separation (AVLIS) was perfect by the Energy Department to select uranium isotops in the sixties. However after spending $ 2 billion to produce uranium for nuclear power plants, the cool war ended and thousands of tons were flooded in the nuclear fuel market Old Soviet arms-grade uraniumThe
As a result, Avalis was less unused until a few years ago, when the hexium technology was lifted and tweeted to pick lithium isotopes.
To do this, the startup will use the laser that can be tune in with a picometer accuracy. The ones that hexium use are relatively low energy – “We’re talking about tattoo removal energy,” Pittson said – but their accurate lets interact with a certain lithium isotope.
Like most ingredients, lithium is not simply a configuration of protons, neutrons and electrons. There are two stable isotopes in the weaving: lithium -6, which contains three protons, three neutrons and three electrons; And lithium -7, which contains an additional neutron. Each isotope has its own signature, so to speak, it has been expressed as a wave function. Think of how different people produce different waves when visualizing the computer. Hexium alone tunes its lasers to contact the wave function of the lithium -6.
“It will flow exactly by a lithium -7 atom, it will not be noticed,” Jerot said.
To separate from lithium -6 to lithium -6, the company will burn its lasers in metal -steep clouds. When the laser hit a lithium -6 atom, it will become ion. The ioned atom will then be drawn on an electrically charged plate where it will be concentrated in a liquid and will fall into a hole, such as the outer water beads of the glass.
Hexium can then pack Lithium -6 and sell it to fusion companies, which will use both metal for tritium fuel and protect their pilots and commercial reactors from harmful radiation. The rest of the lithium -7? It will be sold to the operators of conventional nuclear reactors, which uses isotopes as a protective addition to cool water.
Over the coming years, hexium will use its seed funds to create and manage a pilot plant. If everything is fine, the hexium design will make the transcript in modular fashion to produce ten to several hundred kilograms of lithium -6.
“We do not have to make any costco or football stadium size,” Jacobson said. ” “We can do it at any convenience of the size of a starbox and we achieve good economy in very small size and then we simply parallel our process.”
